<p>The invention describes a method and a system for monitoring the autonomic nervous system (SNA) of a subject (10), comprising: acquiring at least one physiological signal comprising W heartbeats, generating a datum which is a function of the variability of the heart rate (VFC) on the W heartbeats, the VFC comprising W-1 RR intervals separating two consecutive heartbeats detected respectively at the moments tk-1 and tk, each RR interval having a duration with a value aκ = tκ − tκ-1 where k = (X- W+2)... X; using at least one microprocessor to calculate at least one parameter from among the parameter TAS(tx) representing the level of activity of the sympathetic system and/or the parameter TAP(tx) representing the level of activity of the parasympathetic system; and/or other parameters, and/or the parameter NS(tx) representing a stress level of the subject at the moment tx and calculated using the equation NS(tx) = 100 +TAS(tx) - TAP(tx); and supplying a datum representative of said at least one parameter.</p> |
